Christian Gérard - Construction of Hadamard states for Klein‐Gordon fields
- document 1 document 2 document 3
- niveau 1 niveau 2 niveau 3
Descriptif
we will review a new construction of Hadamard states for quantized Klein-‐Gordon fields on curved spacetimes, relying on pseudo differential calculus on a Cauchy surface. We also present some work in progress where Hadamard states are constructed from traces of Klein-‐Gordon fields on a characteristic cone. (Joint work with Michal Wrochna).
